Last evening we organised the 7th Docker user group meetup in Bern. The kind folks from Die Mobiliar hosted and sponsored the event. There was incredible participation for this meetup and about 160 people joined in.

There were 3 talks held in the meetup, Die Mobiliar and SBB shared their experiences about using Docker in production. The third presentation was from Swisscom, who talked about using Docker in Cloud Foundry. The speaker took the opportunity to release the Docker support feature for the Swisscom Application Cloud. The slides are in line, in the respective names.  Continue reading

Challenges with running ROS on Kubernetes

27. April 2016 / / 2 Comments

The goal of the Cloud Robotics initiative of the SPLab is to ease the integration of Cloud Computing and Robotics workloads. One of the first things we need to sort out is how to leverage different networking models available on the cloud to support these mixed workloads.

In this blog post we’ll see one little handy trick to have ROS nodes run as pods (and services) in any Kubernetes cluster so that they can transparently communicate using a ROS topic.

InfluxDB design guidelines to avoid performance issues

27. April 2016 / / 1 Comment

Cyclops, ICCLab’s Rating-Charging-Billing solution for Cloud providers, capable of collecting usage records from both OpenStack and CloudStack, has been working with time series data from the very beginning. Our choice for database technology that is highly optimised to handle such data was InfluxDB written in GO.

Time series data is generally a sequence of data points – in our case either Usage Data Records or Charge Data Records. These datasets often have hundreds of millions of rows, including timestamps and large quantities of immutable fields. Entries do not typically change after they are added to the database, where new entries are being appended rather than operated on. Continue reading

Experience with Neutron High Availability (HA) in Openstack

21. April 2016 / / 0 Comments

For the Zurich FIWARE node, we’re setting up a Kilo High Availability (HA) deployment – we’re transitioning from our current Icehouse (non-HA) deployment.

Kilo HA is recommended as there is a general understanding within the project that the HA capabilities are now ready for production use. However, there is no single Kilo HA – there are many different configurations which can be called HA – and in this post, we describe some of the points we encountered while setting up our HA node.

We deployed Mirantis Openstack v7.0 using the Fuel deployment tool, as is used in the project and as we have used before; requiring a HA deployment, we selected the HA configuration in Fuel and we have 3 controller nodes to provide HA. We did have some issues that the deployment did not terminate cleanly, failing in some astute-based post-deployment tests – however, these issues were minor and the system behaved in a sane manner.

20. April 2016 / / 0 Comments

On 23rd March, we celebrated Docker’s 3rd b’day. The lab is actively involved in organising Docker meetups in Switzerland, join the group to learn more about the upcoming events.

This particular meetup was one amongst the worldwide series of events that Docker was supporting. The 3rd b’day celebration event was held by offering free Docker training to the newbies. We had about 55 people who joined in the training and several of them successfully finished the training. Following picture shows the number of people who successfully finished the training and could pin up in the worldwide Docker map.
